Identifying the Cause of Your Car’s Paint Bubbles

Knowing the root cause is the first step to an effective repair. Is it rust bubbling up from underneath? Did the previous paint job trap moisture? Or was it a reaction to a harsh cleaning product?

Moisture: A Common Culprit

Moisture is a frequent offender, often sneaking in through tiny chips or cracks in the paint. This trapped moisture then expands and contracts with temperature changes, creating pressure that lifts the paint, forming bubbles.

Poor Surface Preparation

Another common reason is inadequate preparation before painting. If the surface wasn’t properly cleaned and primed, the new paint won’t adhere correctly, leading to bubbles.

Impact Damage

Sometimes, a small rock chip or even a minor ding can cause paint bubbles. The impact can damage the paint layers, allowing moisture to seep in.

Once you’ve identified the cause, you can begin the repair process.
